Magnum Inverter/PFC Charger 3900W Off-Grid 24 VDC/105Amp PFC Charger RD3924

A remote control is HIGHLY RECOMMENDED with every Magnum Inverter so that the inverter features can be modified and error codes recovered.

Introducing the RD Series Inverter/ Charger from Magnum Energy - a new generation inverter designed specifically for off grid use. The RD Series is powerful, easy-to-use, and best of all, cost effective. It is built in the same chassis as the MS sine wave inverters. The power factor corrected battery charger efficiently charges your batteries even at low AC voltages from low cost generators, while the modified sine wave inverter keeps the cost down.

 
Safe and Reliable: The RD Series is ETL Listed to the stringent requirements of UL/cUL 1741, ensuring that the inverter is safe and reliable.

Easy-to-install: Install the RD Series in four easy steps: Simply connect the inverter's output to your distribution circuits or electrical panel, connect your power cable (AC) to the inverter's easy-to-reach terminal block, connect the batteries, and switch on the power.

Efficient: The sine wave charger efficiently charges your batteries even at low AC voltage, while the modified sine wave inverter keeps the cost down. Additionally, the battery temperature sensor works with the charger for optimum battery charging.

Choices: The RD Series comes in three power models, allowing you to choose the model that is right for you.

Upgradeable memory: The inverter is designed with Flash programming for easy memory upgrades.

Versatile mounting: Mount the RD Series on a shelf, wall, or even upside down.

Lightweight: The lightweight aluminum base and cover also provides noise reduction and corrosion resistance.

Multiple ports: The RD Series provides multiple ports, including an RS485 communication port for network expansion, and a remote port.

Accessible design: The extra large AC access cover with terminal screw block and 360 degree DC connection terminals with covers make this inverter more accessible when it needs to be.

Convenient switches: The RD Series comes with an on/off inverter-mounted switch with an easy-to-read LED indicator.

Expanded transfer relay: 50 Amp transfer service is available on all models.
Buy with ease: The RD Series is backed by a 24 month limited warranty.
